My Guide To Beating Hypoglycemia Review

Highly Recommended

This is one of the best books I have read on this field. The writing style was simple and engaging. Content included was worth reading spending my precious time.

I give this ebook my highest rating, 10/10 and personally recommend it.

Insulin and Synthetic Hypoglycemic Agents

Drugs used for lowering the glucose level in the blood are called hypoglycemic agents. Likewise, substances that raise the level of glucose in the blood are called hyperglycemic agents. Changes in the level of glucose in the blood can be caused by various reasons, the primary cause being diabetes mellitus. Diabetes mellitus is a metabolic disease associated with a high level of blood sugar and as a rule, disturbance of carbohydrate, lipid, and protein metabolism. The most common biochemical condition in diabetes mellitus is ketoacidosis. Insulin and other hypoglycemic agents are used to treat diabetes mellitus. Depending on the condition of the organism, diabetes is classified into two types. Insulindependant (type I), in which there is suppression of endogenous insulin production by the organism itself, and insulin-independent (type II), which results either because of insufficient insulin production, or because of a breakdown of insulin receptors, which is usually a result of other...

Glucose Metabolism Disorders Hypoglycemia

Unlike other body tissues, the CNS relies almost exclusively on glucose as an energy substrate. CNS features that promote its vulnerability to hypoglycemia include its low glucose level (about 25 percent of the serum glucose value), its inability to store significant glucose as glycogen, and the high cerebral metabolic rate (5 mg 100 g brain tissue min) for glucose. yj Thus, for a 1400 g brain, the glucose requirement is 70 mg min. The brain's dependence on glucose, coupled with its limited glycogen stores, results in rapid CNS dysfunction when hypoglycemia occurs and permanent neurological sequelae if it is prolonged. The glucose level at which CNS dysfunction occurs depends on its rapidity of onset, the current level of CNS activity, the quantity of CNS glycogen, and the availability of alternative fuels. The immediate cause of CNS dysfunction is unknown. Although it was initially believed to be due to tissue energy depletion, high-energy organic...

Low Blood Sugar or Thyrotoxicosis

Low blood sugar, also known as hypoglycemia, triggers the very same adrenaline rush reaction that can occur in a panic attack. Low blood sugar can be measured, and a reading below 50 mg dl (or in Canada, 3.5 mmol L) is considered too low. But many people assume they suffer from low blood sugar even when their blood sugar levels are normal because they feel shaky and irritable when hungry, which is relieved by food. In fact, the common feature to panic attacks and true hypoglycemic attacks is a rapid activation of the adrenergic system (adrenaline release), the same system enhanced by thyrotoxicosis. In this way, thyrotoxicosis can be confused for both panic attacks and hypoglycemia. Treatment of these adrenergic symptoms by beta-blockers can relieve most of these symptoms, and correction of the underlying thyrotoxicosis relieves the rest of them.

Directed Neurological Examination Overview

The examination of the patient with altered consciousness begins by ensuring that the patient's vital signs and basic biochemistry are adequate to support brain function. It is essential to ensure that blood pressure, respiration, and oxygen saturation are adequate and that the patient is not hypoglycemic or thiamine deficient before proceeding with the examination outlined later. In many situations (e.g., emergency departments), naloxone is also administered at this point to reverse any putative effects of opiates. The empirical use of flumazenil to antagonize potential benzodiazepine intoxication as a routine measure is controversial because of the risk of provoking seizures or status epilepticus, especially in patients with mixed benzodiazepine and cyclic antidepressant overdoses.

AMPA Receptors as Pharmacotherapeutic Sites

AMPA receptors are widespread in the brain, including most regions of the cerebral cortex, hippocampus, amygdala, thalamus, hypothalamus, brain stem, and spinal cord. The regional variations in expression of the subunits, splice variants, and editing efficiency are apparent and are probably involved in local and global network function. AMPA receptors are being studied as potential therapeutic targets in diseases such as Alzheimer's disease, cerebrovascular disease (preventive and poststroke), epilepsy, schizophrenia, neural trauma, and other conditions involving cognitive impairments. Such promise has been raised by the successes reported for AMPA agonists (AMPAmimetics or AMPAkines) to enhance maze learning in age-associated memory impairment in mice and for antagonists (blockers) to prevent the spread of necrosis in ischemic events. Agonists (such as CX516 and aniracetam) and antagonists of varying specificity for AMPA receptor variants are being studied, with goals of safer and...

Methods to Quantify EE and Physical Fitness in Type 2 Diabetes Mellitus

The results of SenseWear ArmBand were compared to the doubly labeled water (DLW) technique over a period of 10 days in six diabetic patients treated with diet only and or oral hypoglycemic agents 42 . The results of this preliminary study are promising because it demonstrated that the correlation between the armband and DLW reached r 0.9696 (P 0.0014) and the authors hypothesized a narrow limit of agreement ( 100-300kcal day) between the two methods. From a practical point the Sense Wear ArmBand might be used in subjects affected by the metabolic syndrome to gain information about (1) the basal metabolic rate of patients (average EE during resting hours) (2) EE consumed through spontaneous, moderate, or high intensity physical activity (setting different ranges of METs) (3) the status of physical fitness by recording the peak of METs achieved during high intensity physical activity (4) the hours and the quality of sleep (constant or intermittent) (5) the accuracy of a physical...

Theoretical Framework For Understanding Stress Responsive Systems

Perhaps the most important distinction between environmental and physiological stressors is that physiological stressors do not necessarily require cognitive appraisal, emotional evaluation, or conscious awareness to exert their effects. For instance, exposure to infectious agents (bacteria, viruses, toxins, etc.), hypoxia, hypoglycemia, and hypothermia are all examples of physiological stressors that elicit a stress reaction. Clearly, once the seriousness of the physiological challenge passes some identifiable threshold, the individual would normally develop a subjective experience of stress, which may then further activate stress responsive systems. Nevertheless, psychic stressors are qualitatively different than environmental ones and may activate stress responses via distinct pathways (Herman et al., 1996 Herman and Cullinan, 1997).

Sympathetic Nervous System

On the other end of the spectrum would be physiological threats to homeostasis such as hypoxia, hypoglycemia, or hemorrhagic shock that are detected in brainstem structures such as the pons, medulla, and reticular formation. In cases such as these where threat is not necessarily detected by the cognitive or perceptual apparatus of the organism, but rather by alarm systems that continuously monitor peripheral physiological status, the locus coeruleus sends ascending catecholaminergic input to higher brain centers. Such information is then processed by higher cognitive structures in order to encourage behavioral strategies that will alleviate the threat to homeostasis. Thus, brainstem autonomic nuclei such as the locus coeruleus are critical sites of integration for threatening stimuli irrespective of whether the threat originates from higher brain centers or peripheral challenges to homeostasis see Harro and Oreland (2001) for an excellent review .

Norman W Thompson Daryl K Gray

The first recognized symptoms from an islet cell tumor were those caused by hypoglycemia. The first intentional operation performed for an insulinoma was done by Mayo in 1926.1 Unfortunately, his patient had metastatic disease and died within 1 month from continued hypoglycemia. In 1928, Graham in Toronto successfully excised an insulinoma and cured a patient with hyperinsulinism. By 1974, Stefanini and

Other Valuable Uses for Beta Blockers

Beta-blockers are also effective medications to treat high blood pressure, prevent angina or heart attacks in people with cardiovascular disease, reduce the frequency of migraine headaches, and prevent panic attacks. This makes their appropriate use, in thyroid cancer patients, multifunctional. Sara has told me that her beta-blocker has also eliminated her panic attacks and feelings of jitteriness after eating (which she had wrongly attributed to hypoglycemia). In this context, the beta-blocker nicely balances the thyroid hormone suppression therapy (to keep TSH low) that is a mainstay of thyroid cancer treatment.

Food Selection and Meal Initiation

Food selection and meal initiation are controlled mainly by conditioned olfactory, visual, temporal, cognitive, and social stimuli. These are usually highly individuated, especially in humans. Two physiological signals are also known to be sufficient for normal meal initiation. First, small, brief, transient declines in blood glucose supply signal hunger. These declines are not hypoglycemia (i.e., decreases in blood glucose that reduce cellular glucose supply), which rarely occurs spontaneously. Second, certain changes in liver metabolism that occur between meals, such as changes in fatty acid oxidation, are sufficient to initiate eating. Gastric contractions are not signals for meal initiation the referral of hunger pangs to the stomach seems an epiphenomenon.

Mutations in Structural Components of the Oxphos Complexes

Until now, mutations in nuclear genes that encode different complex I sub-units have been the most common mutations described for nuclear OXPHOS genes. Finding new mutations in complex I subunits has proven to be very challenging since it is a giant of the OXPHOS system, consisting of at least 46 different subunits 27 . Nevertheless, several new mutations associated with mitochondrial diseases have been discovered in recent years 28 . Most of these mutations have been associated with severe neurological disorders with lactic acidosis and most often Leigh's syndrome 29 . Unfortunately, for many isolated complex I deficiencies, mutations have still not been mapped, leading us to conclude that there are many unknown factors involved in the structure and assembly of complex I. Although mutations in complex II have also been associated with Leigh's syndrome, they are found to be more important in their association with inherited paragangliomas and pheochro-mocytomas 30 . Recently, the...

In Vivo Animal Experiments

Most of the experimental animal models used in these studies did not reproduce the full range of metabolic and physiologic derangements seen clinically in severe acute liver failure. In addition, there was significant variation in the physiologic, biochemical and survival effects noted in the untreated groups. The baseline variation in outcome, seen in control animals, makes evaluation of the effects of the various interventions difficult. The major experimental animal models studied include those utilizing hepatotoxins, i.e., acetaminophen, CCl4, D-galactosamine, and those with acute transient or permanent liver ischemia, sometimes in combination with partial liver resection. In both instances, however, it is difficult to standardize the degree of liver injury. Complete liver devascularization, although it appears to be more consistently reproducible, it is followed by a degree of rapid and severe deterioration of all vital functions and sepsis, which...

Application of Neural Differentiation Protocols to Pancreatic Differentiation of ES Cells

Considering their different embryologic origins, the common developmental control mechanisms and overlap in gene expression between neural and pancreatic cells (25,32) are quite intriguing. In addition to common developmental mechanisms, there also exists a functional overlap between neural and pancreatic cells. For example, the release of insulin by p cells and release of neurotransmitters by neurons is accomplished through similar mechanisms (48). These similarities suggest a common ancestral origin of insulin producing cells and neurons. In fact, in Drosophila, the ablation of insulin-producing cell clusters located in the brain leads to a phenotype reminiscent of diabetes (49). Moreover, it has been reported that a patient with a brain tumor of a neuroectodermal origin has developed severe hypoglycemia resulting from insulin production by the tumor (50).

Reviews and Selected Updates References

A large number of diseases, at least 70, involve the metabolism of organic and amino acids. Some diseases present as repeated episodes of acute metabolic decompensation, and the central nervous system (CNS) involvement is usually secondary to the accompanying acidosis, hypoglycemia, or hyperammonemia or to the elevated concentration of amino acids. Nevertheless, it is the secondary involvement of the CNS that is important and is the main problem requiring management. Another group of these disorders involves the CNS primarily, with the systemic disease being negligible. Such disorders are difficult to label at the time of initial encounter as either an organic or amino acid disorder because there are no episodes of acid-base disturbance or disturbance of glucose or ammonia metabolism. They can only be diagnosed by specialized biochemical tests. The recent advent of tandem mass spectrometry is changing the practice of neurometabolic diseases since it provides a rapid diagnosis. 1 , y...

Lethal Infantile Mitochondrial Disease or Congenital Lactic Acidosis

Supportive treatment of liver, renal, and cardiac failure is important, along with consultation with a center using experimental protocols. For respiratory chain defects, megadoses of vitamins K and C, coenzyme Q10, L-carnitine, and folic acid have all been tried with controversial benefit. If PDH deficiency is the cause, thiamine and lipoic acid may be therapeutic, because PDH requires these as cofactors. If biotinidase deficiency or multiple carboxylase deficiency is the cause, 50 mg of biotin daily can be given. Fructose-1,6-biphosphatse deficiency and glucose-6-phosphatase deficiency, both gluconeogenic defects, respond to frequent daily and continuous nocturnal feedings to prevent hypoglycemia. There is no effective treatment for pyruvate carboxylase deficiency or partial defects of the Krebs cycle. Correction of the metabolic acidosis and lowering of serum lactic acid is most effective with sodium dichloroacetate (DCA), 15 to 200 mg kg day administered intravenously or orally....

Fatty Acid Oxidation Disorders

In these disorders there are three main presentations (1) acute toxic encephalopathy with episodes of nonketotic hypoglycemia in the first 2 years of life provoked by fasting (MCAD), (2) skeletal and or cardiac myopathies with weakness (carnitine palmitoyl transferase CPT I and II deficiencies, LCAD, LCHAD, SCAD) and low plasma carnitine, and (3) the syndrome of nonketotic hypoglycemia plus very low plasma carnitine levels (

Medium Chain AcylCoA Dehydrogenase Deficiency

Most patients present between ages 3 and 15 months, rarely after 4 years. Phenotypical heterogeneity prevails, ranging from sudden infant death syndrome, to recurrent Reye's-like syndrome, to episodic nonketotic hypoglycemic coma. A common presentation is vomiting and lethargy, followed by fasting, associated with a prior viral respiratory or gastrointestinal infection. Presentation is usually to an emergency department as an acute toxic encephalopathy or coma, with hypoketotic hypoglycemia, hyperammonemia, and abnormal liver function tests. The serum carnitine value is low, and urine acylcarnitines are increased, with a specific profile. Enzyme assay for MCAD activity can be done on cultured skin fibroblasts, muscle, liver, or blood lymphocytes. The differential diagnosis includes other fatty acid oxidation disorders, exogenous toxic encephalopathies, and true Reye's syndrome. Specific management involves intravenous dextrose 10 percent, avoidance of fasting with frequent short...

Carnitine Palmitoyl Transferase II Deficiency

There are two presentations the adult muscular form, in which prolonged exercise induces weakness and myoglobinuria, and a severe infantile form, in which nonketotic hypoglycemic coma without dicarboxylicaciduria, seizures, hepatomegaly, cardiomegaly, and cardiac arrhythmia are accompanied by low plasma and tissue levels of carnitine with increase in long-chain acylcarnitines. The classic adult form is autosomal recessive and usually affects males between 15 and 30 years of age. The serum creatine kinase value is normal between episodes, carnitine levels are usually normal in plasma and tissues, and long-term muscle weakness is rare, although lipid storage may be seen on muscle biopsy. The differential diagnosis includes other carnitine cycle disorders. Management involves supportive treatment of the renal failure and measures to remove the myoglobin from kidney and avoidance of triggering factors-prolonged exercise, exposure to cold, infections, and fasting. Presentation in the...

Stem Cellderived Islets And Intervention Therapy

Despite the high profile of type 1 diabetes and the implementation of new genetic screening programs for families and newborns to identify high-risk individuals, the incidence of type 1 diabetes is increasing worldwide. Type 1 diabetes is an especially insidious disease with clinical symptoms usually not being detected until after the patient's own immune system has destroyed 90 of the total insulin-producing P-cells of the endocrine pancreas (Eisenbarth, 1986 Harris, 1999). Although routine insulin injections can provide diabetic patients with their daily insulin requirements, blood glucose excursions are common, resulting in hyperglycemic episodes. Hyperglycemia represents the major health problem for the diabetic patient, especially long term. When inadequately controlled, chronic hyperglycemia can lead to microvascular complications (e.g., retinopathy and blindness, nephropathy and renal failure, neuropathy, foot ulcers, and amputation), and macrovascular complications (e.g.,...

Treatment of Acute Liver Insufficiency

Microcarrier-attached normal rat hepatocytes were transplanted into rats with acute liver insufficiency following 90 partial hepatectomy. A dramatic improvement in recipient survival and prevention of postoperative hypoglycemia in rats transplanted four days prior to 90 partial hepatectomy were noted. There were no significant differences in animal survival between rats given allogeneic vs. those receiving syngeneic hepatocytes. It takes several days for intraperitoneally transplanted allogeneic hepatocytes to be rejected we thus concluded that only early hepatocyte survival is important in prolonging animal survival in these animals, by providing metabolic support during a time of acute liver insufficiency

Autologous Hsct In Recentonset Autoimmune Type 1 Diabetes Mellitus

Loss of islet p cells occurs over a time span of 3-5 years and is initially balanced by regeneration however, persistent autoimmunity eventually exhausts or overwhelms the regenerative capacity of pancreatic stem cells (27). Clinical symptoms manifest when the number of islet p cells falls below the threshold necessary to maintain glycemic control, but before complete ablation of islet p cells. Patients with residual islet p cells have better metabolic control, are less likely to experience acute hypoglycemic or ketotic episodes, and are less likely to develop chronic complications (28). Therapeutic intervention designed to control autoimmunity in patients with recent onset type 1 diabetes may preserve remaining islets and thus improve disease management.

Pancreas And Islet Transplant For Autoimmune Type 1 Diabetes Mellitus

Although the markedly improved success of islet transplantation with the Edmonton protocol is promising, both the high number of donor islets (requiring two to three donor pancreases per transplant recipient) and the necessity for chronic immunosuppressive therapy remain barriers to widespread clinical application. Also, although indications for islet transplant include severe hy-poglycemia unawareness or severe metabolic instability, intrahepatic islet transplant does not restore hypoglycemic hormonal counterregulation (62). Finally, risk of recurrent autoimmune disease after pancreas or islet transplantation has yet to be adequately addressed.

Testing for Adrenal Deficiency

Sometimes, the cosyntropin stimulation test may not be accurate if there is pituitary or hypothalamic disease as the cause of low adrenal function. Two other tests that work better for this situation are the metyrapone suppression test and insulin-hypoglycemia test. Detailed discussions of these tests are beyond the scope of this book, but they should be well known to the endocrinologists who administer them.

Transplant Rectum

Renal insufficiency.1 ' The goal of pancreatic transplantation is to restore true euglycemia. Despite advances including multiple dosing regimens, ultralong-acting insulin, and continuous infusion pumps, no regimen of exogenous insulin administration reproduces physiologic glucose control. The rationale behind maintaining euglycemia is that this is the only known means of preventing the progression of diabetic complications. In addition, the recipient of a functional vascularized pancreatic graft or functional islet cells has the benefit of freedom from dangerous episodes of hypoglycemia and hyperglycemia. Furthermore, the recipient benefits from freedom from the routine of insulin injections, fewer dietary restrictions, and an improved sense of well-being. These benefits must be weighed against the complications of the

Broda O Barnes Followers

Reams of material, and an entire movement of sorts, support the ideas of late physician Broda O. Barnes, M.D., Ph.D., author of Hypothyroidism The Unsuspected Illness (1976) and Solved The Riddle of Heart Attacks (1976). Barnes also wrote about the alleged connections between hypoglycemia and hypothyroidism. Barnes practiced from the 1930s through the 1970s. His ideas were recycled by Stephen E. Langer, M.D., in a more recent book called Solved The Riddle of Illness, released in its third edition in 2000.

Somatopsychics Definition

The term somatopsychics is derived from the Greek terms soma, meaning body, and psyche, which has become an English term as well. Somatopsychics refers to psychological effects engendered by somatic conditions. Such psychological states range from normal, to mild mood alterations (like irritability due to low blood sugar), to major psychiatric conditions. Everyday life is full of experiences illustrating etiology and effects of somatopsychic mechanisms. Parents are familiar with the mood changes that occur in children when they are hot, tired, or hungry. But people of all ages get irritable because of low blood sugar, heat, and fatigue. Effects of sensory overload, such as noise or heat, and many forms of sensory extremes, including sensory deprivation, are reflected in psychological sequelae. Total sensory deprivation as used in some prisons can lead to psychotic states and hallucinations. On the other hand, enjoyable sensations trigger psychological effects as well. Scents can evoke...

Hepatic Encephalopathy and Cerebral Edema

Diagnosis of hepatic encephalopathy requires the recognition and correction of other disorders affecting cerebral function. Electrolyte and fluid abnormalities, hypoglycemia, azotemia, metabolic acidosis or alkalosis, hypoxia and plasma hyperosmolality need to be corrected. Sedatives and paralytic agents should be avoided during the initial assessment if possible. If sedation, or paralysis, is required, the combination of poor hepatic function and shunting of blood away from the liver may greatly lengthen the drug elimination curve, complicating the interpretation of patient assessment.

Factors That Stimulate or Inhibit Secretion of Growth Hormone

Glucose Inhibit Growth Hormone

The part of the hypothalamus that causes secretion of GHRH is the ventromedial nucleus this is the same area of the hypothalamus that is sensitive to blood glucose concentration, causing satiety in hyper-glycemic states and hunger in hypoglycemic states. The secretion of somatostatin is controlled by other nearby areas of the hypothalamus. Therefore, it is reasonable to believe that some of the same signals that modify a person's behavioral feeding instincts also alter the rate of growth hormone secretion.

Effect Of Spirulina On Fatty Liver

Different extracts of Spirulina (5 of diet composition) were investigated to determine the preventative effects on hypercholesterolemia and hypertriacylglycerolemia.103,121 Oil extracts and defatted extracts were fed to male rats before a single intraperitoneal injection of carbon tetrachloride. The total liver lipids differed significantly, by 28 between the group that had not (50 mg g wet weight) and the group that had (36.2 mg g wet weight) been given Spirulina defatted-extracts. It differed by 30 between the former group and the group that had been treated with an oil fraction. Liver total triacylglycerols (defatted 80 oil 54 ) and cholesterol (defatted 74.5 oil 71 ) were similarly reduced. Liver total lipid, triacylglycerol, and cholesterol levels fell to normal ranges following the treatment.102,103 However, hypotriacylglycerolemic and hypocholesterolemic effects in serum vary among studies, because of variations among the fractions of Spirulina, the dosage effect, the causes of...

The Edmonton Protocol

Evidence for failure of optimal insulin therapy, with severe hypoglycemia, hypoglycemic unawareness or glycemic instability, as measured by end of one year. There is some fall off in insulin independence, with 70 remaining insulin-free at two years and 50 free at three years post transplant. Most patients who return to insulin continue to secrete endogenous insulin (and C-peptide) in sufficient amounts to continue to stabilize risk of hypoglycemic reactions or of glycemic lability, and 88 of patients continue to demonstrate islet function as long as five years post transplant. Islet transplantation has proven to be remarkably successful in stabilizing glucose control to a degree that is vastly superior to even intensive insulin therapy, and patients typically demonstrate normalization of HbAlC.33 As a result of this high level of success, a number of Provinces in Canada

Cranial Nerve Dysfunction

The plasma glucose exceeds 500 mg dl. The reason for this decrease is unclear, but it may reflect the saturation of the carrier-mediated transport of glucose at high plasma concentrations. As a result, it is important to obtain a concomitant serum glucose level at the time of the CSF sample. Although an elevated CSF glucose level (hyperglycorrachia) results from an elevated plasma glucose level, a decreased CSF glucose concentration (hypoglycorrachia) may be due to a variety of causes including hypoglycemia. The other etiologies include bacterial meningitis y (including typical bacteria, tuberculosis, and neurosyphilis), fungal meningitis, certain viral meningitides (mumps),y subarachnoid hemorrhage, carcinomatosis meningitis, chemical meningitis, and meningitis resulting from parasitic organisms (cysticercosis, trichinosis, amebiasis). If 0.4 is used as the lower limit of the normal CSF to serum glucose ratio, values below 0.4 have a sensitivity of 80 to 91 percent and a specificity...

Diagnosing Thyrotoxicosis andor Hyperthyroidism

The challenge for diagnosing either hyperthyroidism and or thyrotoxicosis is similar for hypothyroidism the symptoms can overlap with stress, anxiety, panic disorder, low blood sugar, and cardiovascular diseases. For women, PMS and perimenopause can mask, or be mistaken for, thyrotoxicosis miscarriage or infertility can also result from thyrotoxicosis. In my (Sara's) case, I suffered from thyrotoxic symptoms for more than four years, in the belief that I had low blood sugar and panic disorder. Having been on a TSH-suppression dosage of thyroid hormone most of my adult life, as I aged, I became less tolerant but didn't realize it. A few years later, after Ken and I were married (and he witnessed a few of these episodes), he also noticed one day that my heart was racing. Ken suggested my panic attacks and hypoglycemic reactions might be caused by thyrotoxicosis, which, as discussed previously, makes people oversensitive to their own adrenaline. Of course, this would be the logical...

Control of Symptoms and Biochemical Responses in Functionally Active Gep Net

In the first trial reported by Kvols et al.,16 octreotide subcutaneously (150 g t.i.d.) was observed to present symptomatic responses in 88 and biochemical responses in 72 of patients with carcinoid tumors. The median duration of the biochemical response was 12 months. In 1989 Gorden et al17 performed a meta-analysis of all reported cases of neuroendocrine tumors treated with somatostatin analogs. The meta-analysis indicated symptomatic improvement in 92 and a biochemical response in 66 of the patients.18 More than 50 patients with gastrinomas were treated with doses of 100-1,500 g octreotide day, most of them in the short term. A clinical response defined as control of gastric hypersecretion, pain and diarrhea was observed in 90 of the patients and was accompanied by a significant reduction in serum gastrin and basal acid secretion.18,19 The two most common clinical syndromes related to endocrine pancreatic tumors are the Zollinger-Ellison syndrome resulting from gastrin...

Table 305 Glycogenoses

Clinical Features and Associated Disorders. In Von Gierke's disease, hypoglycemia causes many of the clinical difficulties seen in patients during the first year of life. In this period seizures are frequent, and long-standing hemiplegia and mental retardation occur. Failure to thrive, xanthomas, and isolated hepatomegaly are common, and excessive subcutaneous fat over the buttocks, breasts, and cheeks develops. Affected children usually have a protruding abdomen due to enlargement of the liver. Patients often have recurrent stomatitis frequent infections and may have isolated chronic inflammatory bowel disease. been identified infantile, childhood, and adult. In the infantile type, early symptoms are similar to, but less marked than, those typical of Von Gierke's disease, which is associated with hypoglycemia, failure to thrive, and hepatomegaly. Patients with the infantile type are hypotonic and weak and have poor head control. Juvenile-onset debrancher enzyme deficiency begins...

Recent Progress in Recipient Immunosuppression

Significant side effects that unfavorably alter the risk benefit ratio of islet transplantation. The therapy is currently unsuitable for the majority of patients with type 1 diabetes that are adequately stabilized on insulin. Approximately 10 of patients with type 1 diabetes, however, have severe forms of glycemic lability or recurrent hypoglycemia, and islet-alone transplantation has therefore been restricted to this target population initially. If the myriad of nonimmune side effects associated with current immuno-suppressive therapy could be avoided, islet transplantation could be more broadly applied in diabetes. The side effects of current anti-rejection therapies are due in large part to the reagents' imprecise mechanisms of action, as most clinically approved immunosuppressive maintenance drugs target signaling pathways with a near ubiquitous cellular distribution.

Drug Delivery by Chimeric Peptides

Quantitative measurements of the uptake of cationized proteins as vectors in chimeric peptides were subsequently performed with cationized human albumin conjugated to avidin. Vectors utilizing receptor-mediated uptake must avoid competition by endogenous ligands, as discussed for transferrin above, and also should not display undesirable intrinsic pharmacological activity. Therefore, the use of insulin, with its effect as a hypoglycemic hormone, would be undesirable. Despite these caveats, experimental evidence in favor of the potential utility of insulin peptides in a delivery system has been presented with an insulin fragment one tryptic fragment with low receptor binding affinity (10 of the affinity of insulin) was devoid of a hypoglycemic effect in mice in vivo, yet a chimeric peptide synthesized with horseradish peroxidase was transported into brain in vivo and reached a brain concentration of 1.41 of the injected dose after intravenous administration to mice (105).

AMPA Receptors in Disease

Arecently proposed model of glutamate excitotoxicity highlights the importance of molecular diversity of AMPA subunit expression. It hypothesizes that cells are vulnerable to injury from excessive Ca++ influx after any of a number primary insults affecting the expression of edited GluR2 subunits (such as ischemia, hypoxia, hypoglycemia, or epilepsy). AMPA receptor expression is also altered under conditions of stress in the hippocampus. Perhaps a peak in the expression of AMPA receptors at 20 to 22 weeks of gestation in the human may increase vulnerability to excitox-icity at that time, because AMPA receptors have been shown to increase during the prenatal period in rats, when there is also observed a greater vulnerability to excitotoxic injury. Thus, current evidence supports roles for AMPA receptor involvement in excitotoxic injury through various pathophysiologic mechanisms such as epilepsy, stroke, ischemia, hypoxia, trauma, extreme stress, hypoglycemia, or hypercortisolemia, as...

Carnitine Transport Defect Primary Generalized Carnitine Deficiency

Carnitine fails to be taken up in muscle, heart, and kidney but not liver, leading to insufficient carnitine to support fatty acid oxidation. 70 The kidney fails to conserve carnitine by reabsorption, resulting in very low plasma carnitine levels, which then causes decreased passive diffusion into liver, impairing ketogenesis. Accumulating acyl-CoA compounds become substrates for peroxisomal beta- oxidation, which produces medium-chain fatty acids and dicarboxylic acids, which do not require carnitine for mitochondrial entry. They are then completely oxidized in mitochondria, which is the reason for lack of dicarboxylicaciduria in disorders of the high-affinity carnitine transporter. Treatment with L-carnitine restores plasma levels to normal (40 to 60 pM) but not skeletal muscle. Muscle function can be restored, however, with less than 10 percent normal muscle carnitine levels. This is a rare disorder, and the exact incidence is unknown. There are two major types of presentation, an...

Physical Activity and HRQL in Diabetes

Notably, diabetes patients undergoing intensive diabetes treatment do not face deterioration of their HRQL and psychopathology, assessed by generic and disease-related HRQL questionnaire. A questionnaire of general psychiatric distress (Symptom Checklist-90R 43 ) in the Diabetes Control and Complications Trial 44 and intensive treatment for type I diabetes, coupled with education, are reported to improve HRQL 45 . The quality of life and the psychological well-being in patients with type 1 diabetes participating in an empowerment program improves significantly when compared with the scores measured in patients who refuse participation 45 . In particular, the Vitality and Social Functioning scales of SF-36 are no longer different from population norm after intensive education. Similarly, the Symptoms, Discomfort and Impact scales of the Well-Being Enquiry for Diabetics 46 , reflecting physical functioning, diabetes-related worries and familiar relationships, role functioning and social...

Allogeneic Hsct In Recentonset Autoimmune Type 1 Diabetes Mellitus

In summary, allogeneic HSCT before complete loss of pancreatic islets may cure type 1 diabetes, and the risks of HSCT may be justified in patients with acute, life-threatening hypoglycemic episodes or patients at increased risk of developing life-threatening complications of chronic hyperglycemia. Nevertheless, patients with recent onset type 1 diabetes are at low risk for immediate disease-related mortality, and thus HSCT with MHC class II DQ or DR mismatched donor grafts carries unacceptable risk with available therapies.

The Role of Discovery Versus Confirmation

Certainly, the production of hypoglycemia and seizure disorder was not part of the research protocol for Dr. Janbon and colleagues, and their unanticipated findings fell into the category of exploratory research. Janbon and colleagues would not be criticized for pursuing the surprise findings of their research efforts. The discovery that the antihypertensive agent minoxidil could unexpectedly reduce hair loss, and the finding that the antihypertensive, anti-anginal compound sidenafil can temporarily reverse erectile dysfunction are contemporary examples of the fruits of discovery.

Autoimmune Type 1 Diabetes Mellitus

Type 1 diabetes is characterized by insulin deficiency secondary to progressive T-cell-mediated destruction of insulin-producing pancreatic p cells within the islets of Langerhans. Clinical therapy is supportive blood glucose is controlled by insulin injections, diet, and exercise. Nevertheless, homeostatic maintenance of blood glucose through shifting physiologic conditions is clearly unrealistic, and long-term complications of chronic hyperglycemia, including retinopathy, peripheral neuropathy, stroke, cardiovascular disease, and nephropathy, frequently develop. Although tight glycemic control delays the development of chronic complications (16), the incidence of acute, life-threatening episodes of hypoglycemia is more than three times higher with this treatment (17).

For Assessing Mouse Vision

We measured visual acuity and contrast sensitivity of mice by observing their opto-motor behavior with a computer-controlled threshold measuring system (Prusky et al., 2004). The program (OptoMotry CerebralMechanics, Lethbridge, Alberta, Canada) runs on a dual processor (G5 Power Mac, Apple Computer) controlling four monitors. We tested C57 BL6J mice that had a single copy of the glucagon receptor gene, Gcgr (Gelling et al., 2003). The transgenic Gcgr+ - mice, ranging in age from 1 to 6 months, served as controls for a study of the influence of chronic hypoglycemia on retinal degeneration and visual function (Barlow et al., 2004). Briefly, a mouse is placed on a pedestal situated in the center of a square array of monitors that display a rotating sinusoidal grating. The OptoMotry program controls the speed, direction of rotation, spatial frequency and contrast of the vertical sinusoidal gratings. The luminance of the monitors was 0.4cd m2 at minimum (black) level and 155cd m2 at...

Mitochondrial Toxicity In Children

Hyperlactatemia does occur in the pediatric population (reviewed in ref. 104). There are several concerning reports regarding HIV-exposed but uninfected infants who developed hyperlactatemia from in utero exposure to HAART. One prospective study examined serial lactate levels in 25 infants born to HAART-treated mothers and reported that 92 of infants had elevated lactate levels, with 35 of the cohort demonstrating levels greater than 5 mmol L (105). Only one infant was symptomatic. All of the infants were exposed to NRTIs. There was no correlation with duration of in utero exposure to NRTIs or to other classes of ARVs. Lactate levels were normal in the few mothers who were tested before delivery. The hyperlactatemia resolved in all of the infants by 6 mo of age (105). Another similar study of lactate levels in a group of 20 NRTI-exposed neonates also showed elevated lactate levels in 85 of these infants, none of whom was symptomatic (106). Similar to the first study, lactate levels...

Regulation of Growth Hormone Secretion

Growth hormone is secreted in a pulsatile pattern, increasing and decreasing. The precise mechanisms that control secretion of growth hormone are not fully understood, but several factors related to a person's state of nutrition or stress are known to stimulate secretion (1) starvation, especially with severe protein deficiency (2) hypoglycemia or low concentration of fatty acids in the blood (3) exercise (4) excitement and (5) trauma. Growth hormone also characteristically increases during the first 2 hours of deep sleep, as shown in Figure 75-6. Table 75-3 summarizes some of the factors that are known to influence growth hormone secretion. Under acute conditions, hypoglycemia is a far more potent stimulator of growth hormone secretion than is an acute decrease in protein intake. Conversely, in chronic conditions, growth hormone secretion seems to correlate more with the degree of cellular protein depletion than with the degree of glucose insufficiency. For instance, the extremely...

Product 2254RP

Puzzled, Jabon transmitted these observation to a colleague, Auguste Lou-batieres who himself was engaged in research on the characteristics of seizure disorders in patients exposed to high concentrations of insulin. Loubatieres hypothesized that both insulin and 2254RP produced hypoglycemia. After demonstrating the sequence of hypoglycemia followed by seizures in dogs treated with 2254RP, he verified the induction of hypoglycemia in three female patients by the compound. This collection of research efforts generated the development of the sulfony-lureas as oral hypoglycemic agents in diabetes mellitus.

ACTH Deficiency

The symptoms of central adrenal insufficiency can be subtle. They include poor weight gain, anorexia, easy fatigability, and poor stamina. In patients who have ACTH deficiency, as opposed to primary adrenal insufficiency, symptoms of salt craving, electrolyte imbalance, vitiligo, and hyperpigmentation usually are not observed. More overt manifestations of complete ACTH deficiency include weight loss and shak-iness that is relieved by eating (hypoglycemia). Signs of adrenal crisis at times of medical stress include weakness, abdominal pain, hypotension, and shock.

Methods

Figure 3.1 Genes upregulated (dark gray) and downregulated (dark gray) in blood monocytes of animals with brain injury (left side BH1, BH2, BH3, IG2, IG3, BI1, BI3, BI2, IG1, K1, K3) compared to animals without brain injury (right side C2, H2, S1, S3, C3, S2, H1, H3, K2, C1). The plot shows the hierarchical clustering of 197 regulated genes (y-axis) from blood monocytes of 21 different rat samples (x-axis). At 24 h after brain hemorrhage (BH), insulin-induced hypoglycemia (IG), brain ischemia (BI), kainate-induced seizures (K), 8 hypoxia for 6 h (H), sham surgery (S), or being assigned as untouched controls (C), adult rats were sacrificed and mononuclear cells were separated. Total RNA was isolated and gene expression assessed with Affyme-trix U34A microarrays (3 arrays group). An Injury group of animals that included brain hemorrhage (BH), brain ischemia (BI), kainate (K), and insulin-glucose (IG) subjects were compared to a No injury group that included untouched (C), sham-operated...

Diabetes

If you do happen to have both conditions, an overactive thyroid will often make the diabetes worse and more difficult to control with insulin. Once your thyroid condition is treated, though, you will find it easier to regain control over the diabetes. On the other hand, there are not usually any problems of glucose control directly related to hypothyroidism. If true hypoglycemia is documented by low blood sugar levels (often this is inappropriately diagnosed see Chapter 4) in people with hypothyroidism, it is important to see if the pituitary gland is abnormal, causing both hypothyroidism and loss of adrenal function (causing the low blood sugar). Autoimmune destruction of the pituitary gland, as well as pituitary tumors, might be responsible.

Embryology

The origin of the endocrine and exocrine cells of the pancreas has been a topic of controversy. Despite the functional differences of these cells, observational studies have strongly suggested that both types of cells arise from the same rudimentary endodermal epithelia, a feature that makes the pancreas an integrated organ from a biologic point of view. Experimental data suggest that acinar and ductal cells differentiate from lineage-specific primitive duct-like cells. Endocrine cells appear imbedded in the ductal epithelia during the tenth to fourteenth week, with acinar cell morphology apparent during the third month. Further elucidation of the cellular and molecular signals within the area of the foregut from which the pancreatic buds form provides important information regarding embryogenesis and also has therapeutic implications for a variety of diseases such as persistent hyperinsulinemic hypoglycemia of infancy, diabetes, and cystic fibrosis.

Background

Diabetes mellitus afflicts over 200 million people worldwide, representing the third most common disease and fourth leading cause of death in North America.1 There are two principal categories of this disease type 1 refers to those with autoimmune pancreatic islet destruction and typically manifests in childhood or early adulthood. There are 30 000 new type 1 patients diagnosed with diabetes annually in North America 2 type 2 diabetes typically affects obese individuals with peripheral insulin resistance and reduced insulin secretion. The incidence of type 2 diabetes is increasing rapidly, and accounts for the major impact of this disease. Type 2 diabetes is lifestyle-related, and recent data has established that intervention through combined diet and physical activity with modest weight reduction can substantially reduce the incidence of the disease by up to 40 to 60 over 4 years in those able to comply with therapy.3 The overall cost burden of diabetes and its secondary...

And Hsct

A combined islet hematopoietic stem cell transplant may both restore glyce-mic control and induce sustained immunologic tolerance to transplanted islets. In contrast to patients with recent-onset type 1 diabetes, hematopoietic stem cell transplantation may be justified in patients with labile diabetes or severe hypoglycemic episodes that qualify them for islet transplant. Dose-escalated immunosuppressive therapies followed by autologous stem cell rescue may increase the success of islet transplant alternatively, allogeneic HSCT combined with islet transplant would allow for cessation of chronic immunosuppres-sive therapy after transplant. Although the procedures and methods for such combined transplants are in preliminary research stages, successful combined

Malaria

Systemic signs of malaria include jaundice, retinal hemorrhage, hepatosplenomegaly, fatigue, diarrhea, vomiting, abdominal pain, chest pain, cough, myalgia, and arthralgia. The majority of patients are febrile. Cerebral malaria presents with headache followed by an altered level of consciousness, and convulsions. On neurological examination, upper motor neuron signs are common as is decerebrate or decorticate posturing, delirium, hallucinations, delusions, and disorders of dysconjugate gaze. Coma is often associated with shock, acidosis, noncardiogenic pulmonary edema, hemolysis, anemia, renal insufficiency, and hypoglycemia. These are all potentially treatable complications. W Diagnosis is made by examining a blood smear for parasites. Blood smear should be examined every 12 to 24 hours for a period of 2 to 3 days, and the number of intraerythrocytic parasites should be counted.

The Role of Insulin

The molecular structure of the complicated protein insulin was determined in Cambridge in the 1950s at the Laboratory of Molecular Biology by Frederick Sanger in the course of his first Nobel Prize work. The physiology of insulin and the control of glucose metabolism is complex. Before active insulin is available, a non-active molecule called C-peptide must be cleaved from the parent molecular proinsulin. There is an important basal secretion of insulin, but on the intake of food, insulin granules, stored in the P cells, are released in a pulsatile manner simultaneously from a number of P cells, in amounts relating to the ambient blood glucose concentration in the islets. The timing is critical. If released too early or too late, high insulin blood levels will cause inappropriate, possibly dangerous, hypoglycemia. If not enough insulin is available at the appropriate time, normal glucose metabolism cannot take place and the blood sugar level will rise. There is a considerable reserve...

Focal Slowing

Polymorphic Delta Eeg Pattern

Continuous slowing in the EEG, whether focal or generalized, tends to take the appearance of either rhythmic monomorphic or arrhythmic polymorphic waveforms. These patterns often have differing significance. Continuous focal arrhythmic polymorphic slowing (Fig. 1) usually suggests some type of structural lesion in the underlying subcortical white matter. Abscesses, ischemic strokes, tumors, contusions, and so on, all may produce this pattern. The mechanism for this form of slowing may reflect disordered intracortical connectivity. Even transient functional disturbances, such as migraine and the postictal state, can be responsible. This illustrates the value of follow-up EEGs looking for evolution or resolution of any focal slowing that may be present. Rarely, focal slowing (and even focal seizures) can suggest toxic-metabolic disturbances, especially in hypoglycemic and hyperglycemic states. Continuous focal rhythmic monomorphic slowing, by contrast, is more commonly associated with...

Disease and Enzymes

Test findings should be grouped into two age categories one for neonatal and one for episodes after 6 months of age. In the neonatal period, the disease almost never causes significant hypoglycemia, nor acidosis, ketonuria, or hyperammonemia. Therefore, the presence of coma in a neonate who has nearly normal clinical biochemical findings should immediately suggest MSUD. Definite diagnosis is through determination of amino acids in plasma or in urine, which shows significant elevations of L-leucine, isoleucine, and valine. Leucine concentration in blood is always higher than that of the other BCAAs. BCAAs or BCKAD can be measured either by chromatographic techniques or more rapidly by tandem mass spectrometric determinations. A quick spot test of the BCKA in the urine is a strongly positive yellow flocculation when 2,3- dinitrophenylhydrazine is added. After 6 months of life, when recurrent acute metabolic decompensation occurs, it is accompanied by mild to moderate...

Systemic Disease

Daytime sleepiness and sleep apneas can be observed in various endocrine, neuromuscular and other types of disorders 2, 29, 42, 44, 52 . Examples are hypothyroidism, acromegaly, diabetic neuropathy with autonomic dysfunction, Parkinsonism, Alzheimer's disease, stroke, epilepsy, metabolic abnormalities such as hyponatremia and hypoglycemia due to adrenal insufficiency, Cushing's syndrome, brainstem abnormalities due to inflammation, hemorrhage, trauma, encephalitis, acute bulbar poliomyelitis, and rarely neoplasm. Neuromuscular disorders affecting the spinal conducting pathways, the anterior horn cells, the nerves to respiratory muscles, and the respiratory muscles themselves, such as compression of the cervical cord, muscular dystrophies, poliomyelitis, Guilliain-Barr syndrome, and myasthenia gravis, can cause hypoventilation. Clinical expression is quite obvious in most of the diseases mentioned above. Management includes treatment of the primary disease, and simultaneous addition of...

Glycogenoses

The glycogenoses or glycogen storage diseases are lysosomal disorders in which glycogen accumulates within a number of tissues hypoglycemia usually accompanies the clinical signs. y These diseases are named for the specific enzyme deficiency that occurs in the glycogen metabolic pathway ( iXaibJei 30z5 ), and their ordering follows the enzymatic steps involved in glycogen synthesis and catabolism. y y y y y y y y ' ni 4si y

Adrenal Disorders

Clinical Features and Associated Disorders. The clinical features of adrenal insufficiency are influenced by the site of dysfunction, because PAI affects all of the adrenocortical hormones, whereas SAI only affects glucocorticoids. Thus, hyperpigmentation, salt craving, and hyperkalemia are unique to patients with PAI. Patients with adrenal insufficiency may present acutely or as a chronic condition. Acute adrenal insufficiency is a medical emergency (so-called addisonian crisis) characterized by mental status changes, fever, hypotension, volume depletion, arthralgias, myalgias, and abdominal pain that may mimic an acute abdomen. 101. Chronic adrenal insufficiency may present more insidiously with fatigue, weakness, GI symptoms, amenorrhea, decreased libido, salt craving, arthralgias, and hypoglycemic symptoms. Neurological manifestations can include confusion, apathy, depression, psychosis, paranoia, and myalgias, as well as hypoglycemic symptoms. 102 In addition, a past medical...

Acute Intoxication

The most important therapeutic problem in the setting of acute intoxication is respiratory depression. With higher blood alcohol levels, stupor and coma can occur, yet there are no distinctive clinical characteristics of alcoholic coma. The diagnosis should be suggested by the clinical setting. Respiratory depression is an early feature, so the diagnosis must be made promptly and should be treated in an intensive care unit. Mechanical ventilatory support should be instituted when necessary, and hypovolemia, acid-base balance, electrolyte, and temperature abnormalities must be corrected. Glucose (50 ml of 5 percent solution) with 100 mg intravenous and 100 mg intramuscular should be given if hypoglycemia is suspected. Because alcohol is absorbed rapidly, gastric lavage with activated charcoal is not likely to be of value in preventing a deeper intoxication. Death has occurred with blood alcohol levels of 4000 mg L, and a level of 5000 mg L is lethal in 50 percent of patients. y...

Studies On Extracts

Sasol Ziegler Alcohol Unit Photos

(Planas and Kuc 1968 Oviedo et al. 1970 Akashi 1975 Akashi andYokoyama 1975 Lee et al. 1979 Takaki et al. 1984 Yamada et al. 1985 Medon and Ziegler 1986 Oliveira-Filho et al. 1989 Sincholle and Marcorelles 1989 Levy et al. 1994 Melis 1995).These studies are typically discussed in terms ofthe percentage ofstevioside in the extract,but the potential contribution of other components in the leaf must always be kept in mind. A number of differences in the pharmacology of Stevia extracts and stevioside have been noted. Thus, the extract inhibits glutamate dehydrogenase stevioside does not (Levy et al. 1994). The hypoglycemic effects reported for Stevia extracts are not seen with stevioside (Oviedo et al. 1970 Curi et al. 1986). The potent inhibition of 2, 4-dinitrophenol-stimulated ATPase of rat liver mitochondria by crude leaf extract cannot be accounted for on the basis of stevioside content (Kelmer Bracht, Kemmelmeier et al. 1985).The presence in extracts of glycosides having an...
